[0024] In the present invention, a plurality of distance sensors and a three-dimensional scanner can be installed on the outer peripheral side wall of the detection probe 7. The distance sensor is used to detect the distance between the detection probe 7 and the casting surface in real time, and the three-dimensional scanner is used to scan the size and position of the casting.
[0025] In the specific implementation of the present invention Its working principle is: 1. Casting clamping and fixing: First, the casting is fixed by a clamping device composed of a displacement block 101, a bidirectional screw 102, a displacement plate 103, a clamping plate 104, etc.; two sets of mutually parallel displacement grooves 107 are provided on the testing platform 1, and the displacement blocks 101 are slidably connected in the displacement grooves 107. The displacement blocks 101 are relatively moved by the rotation of the bidirectional screw 102, and the displacement plate 103 is fixedly connected to the upper end of the displacement block 101. The displacement grooves 107 extend out of the testing platform 1 and are fixedly connected with a synchronous sprocket 205, which is meshed with a chain belt. When in use, the driving motor 201 is started, and the driving motor 201 drives the bidirectional screw 102 to rotate, and the bidirectional screw 102 realizes synchronous rotation through the synchronous sprocket 205, thereby driving the displacement block 101 to move, and the displacement block 101 drives the displacement plates 103 to approach each other, and the casting is clamped and fixed by the clamping plate 104 on the displacement plate 103; 2. Determine the size and position of the casting: During the specific operation, the lifting cylinder 6 drives the detection probe 7 to move upward and reach the specified scanning height. At this time, the height of the detection probe 7 is higher than the casting. Then, the lateral displacement device 4 performs multiple reciprocating movements. During each movement, the hand wheel 607 is turned to adjust the longitudinal position of the detection probe 7. The 3D scanner installed on the outer wall of the detection probe 7 performs scanning, thereby transmitting the size and position information of the casting to the operating system (the operating system includes a computer and supporting program software and other equipment or systems); 3. Defect detection of castings: First, turn the hand wheel 607 to position the detection probe 7 at the inner edge of the casting, and automatically adjust the height of the detection probe 7 by the lifting cylinder 6. Then, driven by the lateral displacement device 4, the detection probe 7 moves to the right, and starts to detect defects in the casting during the movement. When the detection probe 7 reaches the other end of the casting from one end, the transmission gear 509 meshes with the spur rack 705 in the adjustment component 8, and then the lateral displacement device 4 continues to move to the right to rotate the transmission gear 509, but the ratchet 504 transmission component 4 08, the longitudinal screw rod 405 does not rotate. After the transmission gear 509 reaches the other end of the spur rack 705, the lateral displacement device 4 drives the longitudinal displacement device 5 to move to the left, and the spur rack 705 drives the transmission gear 509 to rotate. At this time, the transmission gear 509 drives the longitudinal screw rod 405 to rotate through the ratchet 504 transmission assembly 408, and the longitudinal screw rod 405 drives the longitudinal drive block 404, the movable plate 410 and the lifting cylinder 6 to move outward by an end distance, so that the detection probe 7 can detect defects in other positions of the casting.
